REPEATING CLOCK.

SPECIFICATION forming part of Letters Patent No. 6415477, dated. January 16, 1906.

Application filed July 29, 1399. sit-a1 110 725,499. (No model.)

To all whom it may concern:

Be it known that I, ENRIQUE TORRES, acitizen of the Republic of Mexico, residing at Guadalajara, State of Jalisco, Mexico, have invented a new and useful Clock, (Case 0,) of which the following is a full, clear, and exact specification,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to clocks in which the hours and the quarters are struck, and has for its objects to provide a clock of very simple and effective construction.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a front view in elevation of the clock; Fig. 2, a detail view of the bell-hammer for striking the hours; Fig. 3, an edge view of same part; Fig. 4., an edge view of drum containing spring for driving striking mechanism; Fig. 5, a detail elevation of same parts; Fig. 6, a detail plan of mechanism for releasing the striking mechanism; Fig. 7, an edge view of lever for controlling the hourratchet and dial; Fig. 8, a detail plan of said lever; Fig. 9, a detail plan of rocking arm controlling the hour-striking hammer; Fig. 10, a plan of hour-striking hammer and the hammer-actuating pin Wheel; Fig. 11, an edge view of said wheel, and Fig. 12 a detail edge view of wheel shown in Fig. 9'; Fig. 13, a plan of wheel shown in Fig. 11; Fig. 14, a central vertical section; Fig. 15, a front detail view of movable dial; Fig. 16, a front elevation of mechanism operating the hourshammer.

Referring now to the drawings, a is the main arbor of the clock, on which is mounted the single hand I), which is used for indicating the minutes on the fixed dial. -The movable dial cis shown in the drawings as divided into spaces denoting twenty-four hours; but such division of the dial is not necessary to the use of my clock, and the ordinary division of the dial into twelve spaces and a corresponding number of teeth upon the ratchetwheel by which the dial is moved may be employed, if desired.

Rotatably mounted on main arbor a is a drum d, containing a coiled spring 6, having one end fixed to the arbor a, so as to be wound up thereby, and the other end secured to a band f, freely held within the drum. To this drum is secured the bell-tripping pinwheel g, which is toothed to drive a pinion h, mounted on the shaft of an escapement-wheel 't', which is controlled by an anchor j, having control-pallets and a weight k at each end for the purpose of governing the speed of the es capement. The Wheeli is provided on its under surface with two pins 1, with which is adapted to contact an arm m of a rocking controlling latch-lever n, said arm m and pins forming a latch to control the release and detention of the escapement-wheel 2'. Lever n has at the opposite end an arm 0, one end 1) of which is adapted to engage the four cam-' teeth of a tripping star-wheel q, mounted on and turning with the arbor a. The other end of arm 0 is provided with a latch-lug 0", projecting inwardly. On the outer edge of wheel 9 are mounted ten pins 5 of graduated length arranged in an arc of such length and location that the first pin of the series will bear against and be held by the latch-lug T when the latter is held in its normal position by the end 19, fitting into the star-wheel at the bottom of one of the teeth. The first two pins .9 are long and of equal length, the third short, the fourth long, the next two short, the seventh long, and the remaining three short. These pins are adapted to trip the ends of the bell-hammers t, pivoted at u to the frame. 1; are springs bearing against the hammers to return them to place. The pins extend through the wheel g, forming a row of ten pins to of equal length, to which are added two other pins to form a series to correspond to the twelve hours and which are adapted to contact with and vibrate the arm to of an hour-striking hammer 00. A single pin y is mounted on the outer surface of wheel g, near the center thereof, which contacts against a cam-ledge a on a rocking ratchet-lever 1. From the free end of this lever projects an arm 2, on which is carried a toothed springcatch 3. This catch is adapted to engage by the rocking of the ratchet-lever a ratchetwheel 4, rotatably mounted on arbor CL. A detent 5, having a strong spring, is secured to the pin-wheel g and engages the ratchetwheel 4., bearing strongly against it, so as to carry it around with the Wheel 9 and the drum. A spring-pawl 6 is mounted on the controlling ratchet-lever 1 and engages a ratchet-wheel 7, which carries the dial a and is loosely mounted on arbor a. A spring-detent 8 engages ratchet-wheel 7.

On the outer face of ratchet-wheel 4 are two diametrically opposite pins 9. These pins in the revolution of their wheel strike against the end of lever 10, which is pivoted on arm 11"0f the rocking hammer-carrier 12, formed of said arm and arms 13 and 14. The hammer a; is journaled on a'rod 28, held between arms 11 and 13. A spring 15 on arm 1.1 bears on the pin 16 of lever 10 and holds its inner end forward. The outer end of the lever extends over and substantially parallel to an extension 17 of arm 11. This extension is provided with a notch 18, with which is adapted to engage a spring-detent 19 when the hammer-carrier is rocked'forward. The carrier is normally held in its outward or backward position by means of a spring 20, secured to the frame and bearing against a pin 21 on arm 14. The carrier is rocked to its inner or forward position by means of the contact of a pin 22 on wheel 9 against the inclined end 23 of the arm 14 once in every hourly revolution of the wheel.

Ahandle 24is secured to controlling ratchetlever 1 and serves to turn either dial 0 along or both the dial and ratchet-wheel 4 to any hour that may be desired.

25, 26, and 27 are the bells for sounding the quarters and hours, respectively.

The operation of the clock is as follows: The star-wheel q in rotating with the arbor will, as each quarter of an houris approached, lift and rock outward by one of its cam-teeth the latch-lever n until the highest point of the cam-tooth bears on the lever, whereupon the latch-lug 1" will be released from the first of the pins 5 and the wheel g allowed to turn. The release of this pin will not, however, permit the wheel to move far enough to vibrate the hammers, since the arm m, which has been rocked inward by the movement of lever a, will catch and hold one of the pinsl of the escapement-wheel and thereby prevent further rotation of the escapement and of wheel g. When the quarter is reached, the star-wheel q will trip the controlling latchlever 77. and the latter will be rocked back to ing back to its original position carries the latch r into the path or" pins 5, and the second pin will consequently be caught and held by the latch, thus preventing more than one vibration of the hammers.

When the half-hour is reached, two pinsa long one and a short onewill pass the latch, producing two double sounds, and the next long pin will catch on the latch. On the threequarters three short pins will be released, sounding three double sounds. lVhen the hour is reached, the last long pin and theremaining three short pins will be released, striking four double sounds on the quarterbell. Since there are no more pins to engage the latch r, the wheel 9 will continue its rotation. On its continued rotation the pin y will strike againstthe cam-ledge z and rock the ratchet-lever 1, whereupon the springcatch 3 will be retracted into engagement with ratchet-Wheel 4 and will retain said wheel until the detent 5, carried by wheel g, has slipped by one tooth of the ratchetwheel and engaged the succeeding tooth. On the release of the lever by the pin the former will spring back and will carry springpawl 6 against ratchet-wheel 7, turning the same one tooth and the dialoone figure. By this movement of lever 1 at each rotation of the wheel g, which is completed every hour, a new figure will be presented on the dial 0 at the opening. The pins 9 serve to throw the hammer out of line with the pins u. The wheel 4 has twenty-four teeth and thepins 9 are at diametrically opposite points on the wheel, one each for twelve teeth of the wheel. There are twelve pins a. When the lever 1 is rocked and engages and holds ratchet-wheel 4 until detent 5 has engaged a succeeding tooth, wheel Q will continue rotating, while wheel 4 is held still one tooth, and will therefore carry around one more tooth it past one of the pins 9 than it did before. Hence at each hour one more pin will strike the bell-hammer than on the preceding hour, and thereby produce the necessary additional note. WVhen the hour of twelve is reached, the striking will begin again at one. At each rotation of wheel 9 the pin 22 will strike the end 23 of arm 14, rocking the latter and carrying inward arm 11, so as to bring arm to into the path of the twelve pins u. The lever 10 and arm 11 will be held inward by notch 18 engaging detent 19. The pins to will trip the hammer until one of the pins 9 comes in contact with lever 10, whereupon said lever will be turned forward until its other end forces detent 19 out of notch 18 and permits the hammer-carrier 12 to swing back under the action of spring 20. The arm w is thus carried out of the path of pins to, and the hammer will cease striking. On the succeeding hour the pin 9, having been carried back one tooth of its wheel, will not trip the hammer until another pin of the series to has vibrated it.

By means of the handle 24 the dial 0, if out of correct place, can be alone moved to the proper indication, or by a longer swing of the handle both the dial andratchet-Wheel 7 maybe moved to both indicate and strike a new hour.
